Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed July 2,1906, Serial No. 324,527.

To all whom it may concern:

Be it known that I, CLARENCE C. OHRISMAN, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in a Combined Base-Pad and Copy-Holder for Type-Writers, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a combined base pad and copy holder for typewriters, and the object of my invention is to construct a simple, strong, and durable base for typewriters, calculating machines, and the like, which base is padded on both top and bottom, and

to arrange on said base a folding and adjustable copy holder.

A further object of my invention is to construct a padded base in such a manner as that portions thereof may be adjusted so as to enlarge said base in order to accommodate the larger forms of typewriters, calculating machines, and the like.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts, which will'be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my improved base pad, with the copy holder in a folded position thereon; Fig. 2 is a plan view of the base pad, and showing the copy holder swung into position for use to one side thereof; Fig. 3 is a side elevation of the base pad, with the copy holder folded thereon; Fig. 4 is an enlarged section taken on the line 44 of Fig. 1; Fig. 5 is an enlarged cross section taken on the line 5-5 of Fig. 1; Fig. 6 is an enlarged vertical section taken on the line 66 of Fig. 2; Fig. 7 is a detail elevation of one corner of the copy holder, and showing a portion of the retaining spring thereon; Fig. 8 is a front elevation of the base pad with the copy holder folded thereon.

Referring by numerals to the accompanying draw- 1ngs:11 designate the side rails of the base, which are preferably constructed of metal, and perforated in order to lighten their weight, and formed in the top surfaces of the forward ends of said rails are dovetailed grooves 2. Formed horizontally through the rear ends of said rails are the rectangular openings 3, through which slide tongues 4 formed integral with the ends of a cross rail 5, which forms a portion of the rear of the base. Slots 6 are formed through the tongues 4, and pins 7 extend vertically through the ends of the rails 1, and through the slots 6.

Formed through the rear rail 5, adjacent the ends thereof, are the horizontally disposed openings 8, and adapted to slide therethrough are tongues 9, which are formed integral with a transversely arranged rail 10, which normally lies immediately against the rear side of the rail 5, and against the rear ends of the rails 1. Pins 11 pass through the rail 5, and through slots 12 formed in the tongues 9. The under sides of the rails 1, 5, and 10 are padded, or covered with sections of material, such as heavy cloth, felt, or analogous material, as designated by 13, and the tops of said rails are covered with suitable sections 14 of padding material, which is preferably much thicker than the material on the under sides of said rails.

Rigidly fixed to the center of the rail 5, and projecting forwardly therefrom, is an arm 15, the forward end of which is bifurcated, as designated by 15, and the arms formed by this bifurcation curve outwardly to the forward ends of the side rails 1, and the ends of said arms are provided with plates 16, on the under sides of which are formed the transversely arranged dove-tailed ribs 16, which slide in the dove-tailed grooves 2. The arm 15 is provided with a slot 17, the forward end of which divides as indicated by 17, and the slots formed by said division extend through the arms 15.

18 designates an arm made up of parallel members, which are so spaced as that they lit on top and against the bottom of the arm 15, and passing through the rear ends of the parts of said arm 18, is a rivet 19, which passes through the slot 17 in said arm 15. The forward ends of the parts of the armlS are provided with the integral circular plates 20, and arranged between said plates is a plate 21, slightly smaller in diam.- eter than are said plates 20, and thus a groove 22 is formed between the edges of said plates 20. Arranged on top of the upper plate 20 is a semicircular plate 23, which is pivotally connected to the plates 20 by means of a pin or rivet 24 which passes through the centers of said plates 20 and the plate 21. Formed integral with the rear edge of the plate 23 is a hook 25, which rides in the groove 22.

Hinged to the forward edge of the plate 23 is a rectangular plate 26, and formed in the center thereof, by punching the material of which said plate is formed outwardly, is a vertical row of cars 27. A plate 28 is arranged to slide vertically on the front face of the plate 26, the side edges of which plate 28 are bent around the side edges of the plate 26, as designated by 29. Formed in these bent edges 29 are the vertical slots 30, and extending theretln'ough are screws 31 carried by the rear side of the plate 26, and on which screws are located thumb nuts 32. This arrangement provides for the vertical adjustment of the plate 28 upon the plate 26, and the locking of said plates together at any point in the adjustment. A copy holding spring 33 extends transversely across the top of the plate 28, the ends of which spring are formed into the coils 34, and secured to the upper corners of said plate 28. An inverted U-shaped spring 35 is provided with coils 36 at its lower ends, and said coils being secured to the top of the plate 23, the upper end of said spring being adapted to engage beneath the ears 27 so as to adjust the inclination of the copy holding plates 26 and 28.

When my improved device is in use, the padded base is positioned on top of a desk, or table, and the base, or ieet of a typewriter, or calculating machine, rest upon the pads 14 on top of the rails 1, 5, and 10. The copy holding plates 26 and 28 when not in use are swung over onto the arm 18, and said arm carrying the plates is moved rearwardly to its limit of movement until the pin, or rivet, 19 is at the rear end of the slot 17. Thus, the copy holding plates and arm 18 occupy an out-ol-the-way position upon the padded base beneath the typewriter. The pads 13 on the under sides of the rails l 5, and 10 prevent the base from scratching the desk or table, and the thick pads 14 on top of said rails support the machine carried by the base, and act as cushions to reduce the vibration of the machine while in operation.

When the copy holding plates are swung outwardly for use, the arm 18 is pulled forwardly and swung to one side until the rivet l9 occupies the outer end oi the corresponding one oi the slots 17, and the plate 23 is now shifted upon its pivot pin 24 until the plate 26 is brought to the desired angle relative the arm 18. The plate 26 is held at the desired angle vertically by means of the spring 35 engaging one of the cars 27, and the plate 28 can be adjusted vertically upon the plate 26, and locked at the desired position by manipulating the thumb nuts 32. There is suflicient friction in the hinge between the plates 23 and 26 to overcome the resistance offered by the spring 35, so that when the plate 26 is elevated, said spring merely acts as a support therelor. The book, or sheet, containing the matter to be transcribed or written on the machine is now engaged beneath the spring 33, and is there held in a iirm manner and in a position convenient to the operator. The side rails 1 may be moved outwardly relative the rail 5 and ends of the arms 15, and the rear rail 10 may be moved outwardly, I

thus enlarging the base in order to receive the larger forms of typewriters and like machines.

A device of my improved construction is very easily adjusted, provides a substantial base for typewriters and the like, is padded to prevent the scratching or marring of the desk or table, and provides means whereby the copy is very conveniently held in the desired position.

The copy holder, when not in use, may be folded and moved into an out-of-the-way position beneath the machine located on the padded base, and said copy holder can be easily adjusted to any angle and swung to either side of the machine.

Although my device is intended ordinarily to be placed loosely under the machine, it can also be fastened to the machine itself so as to become a permanent part thereof, or it may be placed loosely or fastened permanently above or below the base-board on which such machines usually rest.

I claim:

1. The combination with an expanding base, of pads located on the top and bottom of said base, and a cop holder adjustably connected to said base; substantially as specified.

'2. The combination with an expanding padded base, of an adjustable copy holder; substantially as specified.

3. The combination with an expanding base, of pads located on the top and bottom of the parts of said expanding base. and an adjustable copy holder connected to said base; substantially as specified.

-l. A base for typewriters and the like, constructed with a frame adapted to be expanded and contracted. pads arranged on the tops and bottoms of the parts of said frame, an arm arranged to slide on said base,- and a copy holding plate adjnstably carried by said arm; substantinlly as specified.

5. A base for typewriters and the like, constructed with a skeleton frame adapted to be expanded and contracted. and pads arranged on the tops and bottoms of the parts of said frame; substantially as specified.

In testimony whoreol', I have signed my name to this specification, in presence of two subscribing witnesses.
